Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

The fungibility of Nano - is it an issue?

In a recent video (link includes timestamp) by Andreas M. Antonopoulos he gets asked to play "devils advocate", and expose some of the vulnerabilities of BitCoin that can be exploited by banks and governments to throw the system out of balance.
Antonopoulos mentions that the base-layer blockchain of BitCoin does not have sufficient privacy/anonymity functionality. He then goes on to explain how this effects the coins fungibility, and thus how "dirty BitCoins" becomes less valuable than "fresh BitCoins" straight from a new block. This is bad, because it affects the coins fungibility, which is an essential function for money.My question/concern, what is Nano doing to combat an issue like the one described in the video? Is this cause for concern, or are crypto-currencies redefining the way money works in such a way that this issue is irrelevant somehow? I'm not an economist, so I have quite a limited understanding of these things thus why I'm asking you all for opinions/knowledge/insight :-)
EDIT: Wow, lots of response in here, thanks a lot everyone for sharing your opinions/knowledge/insight!

I got fired 3 week ago and got into depression, one of my best friends is a crypto trader. Instead of feeling shitty he want to teach me everything about crypto and he said that it might help me to understand the normal 9-6 job life is not the only way. here are the tips and resources he gave me:

i’m sharing it here because i’m sure that there are other people in my situation too and it will be great if i can help you exactly like how my friend helped me.
What i’m sharing here is what i wrote on my notebook while he was pitching the basics of crypto trading, I summarized it into few lists so it will be easier for you to follow:
General tips:
  1. If your mom send you a message asking “how to buy bitcoin”? it means you need to sell yours (not to her of course :P)
  2. Don’t put all your money on the exchange (he lost in the past some money on mt.gox).
  3. If you’re too lazy to print a paper wallet or so cheap you can’t buy Trezor, so don’t cry if you make some stupid mistakes and lose your login details/ get hacked.
  4. Don’t be afraid from charts, After you will get into trading you will find technical analysis like a children’s game, you just need to look for shapes and mark a line to understand where the risk is and than use your instincts, your brain(he claimed i don’t have any) and some useful new resources (i share them later on).
  5. there is too much information, if you will try to focus everything it will kill you and you will spend most of your profits on Advil. arrange yourself a useful resources and a comfortable working environment.
  6. Listen to Lofi while you trade/make decisions.
  7. don’t join random telegram groups or pump and dump groups. no-one open a traders group and invite you just because you have a beautiful smile. 97% of them have hidden interest. Try to attend for a local bitcoin meet up in your hometown or near by and than meet REAL people and REAL traders. Ask them if they have a friends traders group and ask to join, If they don’t agree say the
Trading tips:
  1. Altcoins - Vs. Bitcoin and Vs. USD: it's important to analyse the price against Bitcoin and against USD as well. Most major altcoins have huge USD trading
  2. What goes down – does not necessarily go up again: “I’ve seen Altcoins like Aurora which came down 99.99% of its record”.
  3. Day trading is a job. Consider the time spending on it when calculating your gains and losses.
  4. Don’t put all of your eggs in one basket: Diversify your crypto portfolio, and it's not shame to hedge to cash sometimes
  5. don’t risk something you can’t afford to lose.
resources:
“Give a man a good signal and he made profit for day, Teach him how to trade and will make a profit for a day “ (I made it now… And I wonder why I got fired) :P
He shared with me many of his resources and said that I need to check them to understand which one are useful for me and which isn’t.

I'm donating 25 Bitcoin to good causes this Christmas. Join in and give Bitcoin this Christmas (day 9)

Goal

During December I will donate 25 Bitcoin, 1 each day leading up to Christmas, to a cause suggested by Bitcoin. It can be a charity, open source project, crowdfund or anything else.
 
I am hoping that these daily posts and donations will encourage others in the community to give Bitcoin this Christmas. Especially people who have benefited from the rise in price recently.  

Get involved

Submit a suggestion in the comments of a cause you would like to see donated to. Also post a link to their Bitcoin donation page (not address) if possible. Even if your suggestion is not donated to by me this month hopefully it may be seen by others here who may choose to donate.
 
Each day I'll pick a cause from the suggestions, likely the most upvoted one, and donate 1 Bitcoin to them. I'll ignore any scams, begging, college fund requests etc.

I'm donating 25 Bitcoin to good causes this Christmas. Join in and give Bitcoin this Christmas (day 14)

Goal

During December I will donate 25 Bitcoin, 1 each day leading up to Christmas, to a cause suggested by Bitcoin. It can be a charity, open source project, crowdfund or anything else.
 
I am hoping that these daily posts and donations will encourage others in the community to give Bitcoin this Christmas. Especially people who have benefited from the rise in price recently.

Parallels between two disruptive technologies: Internet & Blockchain – Part I

Parallels between two disruptive technologies: Internet & Blockchain – Part I
[The original article appeared on: https://block.co/blog/]
The emergence of disruptive technologies is always complemented by the creation and development of new models, mostly resulting in new economic concepts and business structures. The rise of the internet over 30 years ago, laid the foundation for the creation of new markets, for instance, that book store that sells all publications from around the world — Amazon. Or new concepts like the ‘Instant gratification’ that contributed to the introduction of business models like Netflix, finally allowing consumers to get instant access to films and series.
Blockchain is bound to create new models in all fields that regulate our lives, from a financial perspective to the regulation of infrastructures facilitating interactions and transactions in a way that would not be possible without the internet. This is one of the reasons why it is often referred to as the next generation of the internet or Web3, where WWW revolutionized information, Web2 facilitated interactions and now Web3 has the potential to innovate agreement and value exchange structures using the internet in a decentralized manner.
From a technological perspective, the similarities between the two are impressive.
We are currently believed to be in what were the early stages of the internet, with similar challenges around scalability, costs, and education, limiting the development of breakthrough applications and mass adoption. These internet challenges were resolved over time, therefore we should expect a similar progression in Blockchain.

https://preview.redd.it/bvdjgzt9jg451.jpg?width=577&format=pjpg&auto=webp&s=a1e9b81b2d5bcbe629b7f414c4a19bafab9373d0
In 1996, major internet service AOL could not manage a high volume of Internet users and went down for nineteen hours. Gradually the average internet speed in the US went from 50Kbps in 1999 to 18.7Mbps of 2017. Similarly, in 2017 the Ethereum blockchain failed to sustain the spike of on-chain transactions caused by the famous blockchain game CryptoKitties and the platform suffered the most serious network clog to date. These failures are necessary to the development of technology. Just like it was clear in 1996 that the internet had to face a scalability issue, it’s been evident for years now that blockchain also has to find ways to deal with the problem. Developers, programmers, experts, and academics are all working on the improvement of the system but there won’t be a definite solution, just like there wasn’t for the internet.
As popular Bitcoin expert and educator Andreas Antonopoulos mentioned in his book The Internet of Money, “Scale is not a goal to achieve; it is a definition of what you can do with the network today.” Scalability was built on the internet based on layers on top of the basic protocol and it looks like this will be the possible progression for the blockchain too. The Lightning Network, layer2 or off-chain protocol, is paving the way for Bitcoin fast and small payments along with a major focus on providing full privacy to transactions. Many believe in this respect we are still in 1994 Internet time, when the TCP/IP, HTML, and FTP were invented, leading to the successful business models represented by Facebook, Airbnb and Uber later. In the blockchain, breakthrough Dapps have yet to appear and will emerge in the coming years.
User Interface will help drive adoption in the same ways it helped the internet. At the time of the Arpanet, the technical foundation of the internet, the system was difficult to use for both nontechnical and technical people. The search functionality relied on an IP address and navigating the internet meant inserting a long string of numbers in order to find what you were looking for. It was easy to get confused, mistype numbers, etc. When the switch between the IP address and the URL happened, it became easier to navigate the web thanks to a more efficient and user-friendly experience overall.
Blockchain usage and benefit are still clunky. We still need a 12 or 24-word phrase to access a private cryptocurrency wallet and send a transaction to a long string of numbers (just like it happened with the early internet addresses) to validate it. All of this will disappear once user interfaces will be given the right attention and mass adoption will likely benefit from a system easier to use. It is clear that in the blockchain development more focus has been given so far to make the technology more secure, reliable, and robust at the expense of the user experience. Once the strength of the network/system is secured there will be a shift of interest in developing the interface with a resulting better user-friendly experience. Maybe it’s the right evolution and one that will bring a stronger technology structure overall.
Adoption is another important parallel we can highlight, not only with the Internet but with all the disruptive technologies previous to the World Wide Web. It took 46 years for electricity, 35 years for telephone, 14 years for TV, and 7 years for the Web to reach 25% of global market penetration. We can expect a similar growth trajectory to happen in the cryptocurrency/blockchain space, perhaps at a faster rate since the world is more connected now, thanks to the already existing internet interactions.
Stay tuned because in part two of this blog we will explore the parallels between the technologies in education, capitals, and start-ups and the decentralization of the blockchain as the main aspect that will revolutionize the Internet as well.
In the meantime, blockchain as a distributed ledger for a secure network of transactions is finding wide adoption as is the case for academic and ID credentials embraced by The University of Nicosia and Block.co. The University of Nicosia and Block.co can help provide the necessary technical expertise to follow the whole process from creation to publication on the blockchain where the document will be safely stored for life and where it can be independently verified by any third party. They were the first ones to do it globally as early as 2014.

I'm donating 25 Bitcoin to good causes - UPDATE

Goal

At the start of December I pledged to donate 25 Bitcoin, 1 each day leading up to Christmas, to a cause suggested by Bitcoin. This was done publically in the hope to inspire others to donate too, especially people who have benefited from the rise in price recently.
 
It took a long time to read every comment, private message and to check everyones suggestions. Unfortunately not many suggested charities accept Bitcoin. I am posting this update so people can make suggestions for the last few donations and see a list of causes donated to so far.
 
I am hoping that this post and donations will still encourage others in the community to give Bitcoin to good causes.

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency

As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin.
Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin.
We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.

Community Terminology

Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin.
HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market.
TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down.
FUD: Fear. Uncertainty. Doubt.
FOMO: Fear of missing out.
Bull Run: Financial term used to describe a rising market.
Bear Run: Financial term used to describe a falling market.

What Is Bitcoin?

Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream.
Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.

A Brief History

Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began.
I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).

What Is Blockchain?

Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions.
The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain.
For more information regarding blockchain I’ve provided more resouces below:

What is Bitcoin Mining

Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info).
Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.

How do you Purchase Bitcoin?

The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin.
Popular exchanges include:
  • Coinbase
  • Kraken
  • Cex
  • Gemini
There’s tons of different exchanges. Just make sure you find one that supports your national currency.

Volatility

Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.

Transaction & Network Fees

Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward.
Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.

Security

In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.

Two-Factor Authentication (2FA)

Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.

SMS Authentication

The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.

Authenticator

The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator.
If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device.
Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).

Hardware Wallets

A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage).
Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor.
Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box.
I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.

Technical Aspects of Bitcoin

TL;DR
  • Address: What you send Bitcoin to.
  • Wallet: Where you store your Bitcoin
  • Max Supply: 21 million
  • Block Time: ~10 minutes
  • Block Size: 1-2 MB
  • Block Reward: BTC reward received from mining.

What is a Bitcoin Address?

A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.

What is a Bitcoin Wallet?

As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack).
My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion.
After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.

What is Bitcoins Max Supply?

The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).

What is Bitcoins Block Time?

The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of.
Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds.
For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.

What is Bitcoins Block Size?

There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB.
There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction.
Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB.
On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.

What is Block Reward?

Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.

Technical Aspects Continued

Understanding Nodes

Straight from the Bitcoin.it wiki
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain.
For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.

What is a Fork?

A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.

Soft Fork vs Hard Fork

The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain.
During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain.
Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain.
Examples of Bitcoin hard forks include:
  • Bitcoin Cash
  • Bitcoin Gold
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.

A Case For Bitcoin in a World of Centralization

Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.

Final Conclusions

Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally.
Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions.

We are averaging 2,000 new subs daily.

We just celebrated the 350,000 mark 5 days ago and today we are over 360,000. Nice to see this sub and the Bitcoin community in general growing this big and this fast.
If you are one of those many just coming in, welcome! I'm sure you'll find this place very interesting, fun and informative. We are here to help you to better understand what Bitcoin is and and how it works, and for ourselves to keep learning. This is my welcome post for newbies:
When you come asking when is a good time to buy, the answer is: Buy now, always Hodl in FUD times (Bitcoin has "died" many times, but Moneybadger don't care, buy the dips and never panic-sell, stuff like: "China ban Bitcoin...again!" will keep happening again and again.
Here's Bitcoin's response to Jamie Dimon. Stick to the real Bitcoin through all the 'forks' and 'splits' that accomplish nothing but new mediocre, unsafe and centralized altcoins, strengthen/immunize Bitcoin and give you free altcoins to buy more Bitcoin.
All Central Powers look silly trying to control or ban it. Learn from history and listen to this absolute Boss. There will never be enough Bitcoin for every existing millionaire to own just ONE SINGLE BITCOIN, Total number of millionaires (in USD value) worldwide is around 33 million. Get one while you still can.
Also relax, you are actually an early adopter if you start investing today, mentally prepare yourself for healthy and expected market volatility/dips/corrections/"crashes" (check out this amazing 'Corrections Trends Perspective') and remember all this regarding Bitcoin investment:
Never try to time the market. Dollar cost average by buying what you can afford to lose every week.
It is always a good time to buy Bitcoin if you are hodling long term and not just for day trading, so this is a great strategy. Remember that Bitcoin has practically been up most of the time, and the road to the moon is paved with minor corrections (Bitcoin is never really "down" when you zoom-out).
Everybody parroting: "The bitcoin bubble is about to pop" since 2009, don't know that bitcoin is a decentralized system with mathematically fixed, deflatioary and limited supply currency and its growth is exponential.
So is not farfetched to say that it will be at 100,000 by 2020, since it came from less than $1 to $5,000 in less than 10 years, and it hasn't even hit the bottom part of the exponential 'S-Curve' of adoption. Check out this great 2017 MIT study: "The Cryptocurrency Market Is Growing Exponentially". Patience pays, don't listen to the "Expert Analysts on MSM".
Bitcoin is a Moneybadger that get's stronger and immunized with every new attack and this broad picture of its price since infancy (1 year candles on a logarithmic scale) shows Bitcoin growth is not in a "bubble" right now. Learn the difference between Inflation (dollar) and Deflation (Bitcoin) and just take a look at the fiat >20 trillion (and growing fast) debt clock to get a visual shock of unlimited fiat supply (vs limited Bitcoin/Gold supply).
Bitcoin has outperformed every other currency, commodity, stock and asset since its inception in 2009: "2017: Bitcoin Beats Stocks, Bonds, And Gold, Again”. Bitcoin, the Moneybadger, is the first unseizable store of value in human history, unlike gold, equities, or fiat, it can't be confiscated if stored correctly. How banks think blockchain will disrupt their industry.
Also, remember its fixed, limited supply of 21 million coins ever, there are just ~4.5 million (~20%) bitcoins left to be mined till 2140 and the production will keep decreasing ("halving") every 4 years till then. So, remember this and don't wait for the Bitcoin "bubble" to burst or for the price to drop significantly again, because you could be waiting forever:
“The best time to buy bitcoin was a few years ago, the second best time is always now”.

Bitcoin is a worldwide-distributed decentralized peer-to-peer censorship-resistant trustless and permissionless deflationary system/currency (see Blockchain technology) backed by mathematics, open source code, cryptography and the most powerful and secure decentralized computational network on the planet, orders of magnitude more powerful than google and government combined. There is a limit of 21 million bitcoins (divisible in smaller units). "Backed by Government" money is not backed by anything and is infinitely printed at will by Central Banks. Bitcoin is limited and decentralized.

Bitcoin ETF? Really?? Banksters are the problem. Bitcoin is the solution.

Trust. The banksters got that name for good reasons: they're know criminals. There are now two classes of people in the US: banksters, and those who must obey all laws or face jail and/or penalties.
Examples include, but are in no way limited to:
https://en.wikipedia.org/wiki/Forex_scandal
https://en.wikipedia.org/wiki/Libor_scandal
https://www.theguardian.com/world/2011/ap03/us-bank-mexico-drug-gangs
Are you willing to trust people like that to hold your Bitcoins for you? If so, what's the matter with you?
Banksters are the problem. Bitcoin is the solution.
"Your keys, your Bitcoin. Not your keys, not your Bitcoin" -- Andreas Antonopoulos
Then, there's the possibility that the fund (ETF) you put your money into is being run by another Bernie Madoff kind of person who will send you quarterly statements, but hasn't actually invested a dime of your money.
https://en.wikipedia.org/wiki/Bernard_Madoff
Before you go spouting off about regulators and auditors, keep reading:
It has been well known for some time that the government regulation agencies have a "revolving door" with the very entities they're supposed to be regulating. People often leave government to go work for the places they were supposed to be regulating. Sometimes people leave the banks to go regulate their "buddies". Again, are you able and willing to trust them? Not me.
https://www.newyorkfed.org/medialibrary/media/research/staff_reports/sr678.pdf
https://en.wikipedia.org/wiki/Goldman_Sachs#Personnel_%22revolving-door%22_with_U.S._government
Ask yourself, "Where the hell were the auditors and regulators during Bernie Madoff's caper?"
Trust is just one of many reasons why a wise person should be very cynical about ETFs in general, and about Bitcoin ETFs specifically.

I'm donating 25 Bitcoin to good causes this Christmas. Join in and give Bitcoin this Christmas (day 16)

Goal

During December I will donate 25 Bitcoin, 1 each day leading up to Christmas, to a cause suggested by Bitcoin. It can be a charity, open source project, crowdfund or anything else.
 
I am hoping that these daily posts and donations will encourage others in the community to give Bitcoin this Christmas. Especially people who have benefited from the rise in price recently.  

Get involved

Submit a suggestion in the comments of a cause you would like to see donated to. Also post a link to their Bitcoin donation page (not address) if possible. Even if your suggestion is not donated to by me this month hopefully it may be seen by others here who may choose to donate.
 
Each day I'll pick a cause from the suggestions, likely the most upvoted one, and donate 1 Bitcoin to them. I'll ignore any scams, begging, college fund requests etc.
 
I will try to send donations as fast as possible but there may be times where I have to do more research or checks to verify the suggestions are legit.  
If you wish to give but don't have the time to check Reddit for the rest of the month you can send Bitcoin to my address:  
34WbSyrtibUJiFbRa7ukLC8RGdFMnQRn4b  
I will divide the extra Bitcoin sent to that address by 25 and donate it to each of the chosen causes on the 25th or the 26th.
Thanks to the people who have donated to my address so far.

Proof of funds

Note that the address above doesn't contain 25 now due to sending donations so the funds moved to change addresses. You need to verify it using Trezor.

Warning: Don't send to addresses I have without checking donation pages first. Some of those were temp wallets produced by their payment processor.
 
P.S. I don't donate to individuals so please don't post or PM.
 
P.P.S I have not seen any suggestions yet for charities dealing with addiction. It would be great if we could get some suggestions for alcohol, drug or gambling addiction.
 
P.P.P.S It would be good to suggest causes that Pineapple Fund are NOT donating too as my donations are small compared to his and could make a bigger impact elsewhere.

BSCoretabs shills are vandalizing Wikipedia to smear Roger Ver with false quoting, missparaphrasing and accusations.

I've come across an instance of this behavior on the Andreas Antonopoulos https://en.wikipedia.org/wiki/Andreas_Antonopoulos article, where they keep insisting that:
Roger Ver derided Andreas Antonopoulos for his public speaking
The cited tweet (citation 23) in question actually says:
Andreas is one of the most eloquent speakers on the topic of Bitcoin
This kind of editing is probably done all across Wikipedia, and I would advise Roger to hire a consultant to monitor Wikipedia, file complaints, get trolls banned and correct intentionally malicious false representation, smearing, slander, etc.
I'm not a Roger fan myself, but I don't go vandalize wikipedia smearing/slandering/misrepresenting somebody I don't like.
